Keithley 2000 Calibration Manual

:STEP7 (:CALibration:PROTected:DC:STEP7)
Purpose To program the 10kΩ 4-wire comprehensive calibration step.
Format :cal:prot:dc:step7 <Cal_resistance>
Parameter <Cal_resistance> = 9E3 to 11E3 [Ω]
Description :STEP7 programs the 10kΩ 4-wire resistance comprehensive calibration
step. The allowable range of the calibration resistance parameter is from 9E3
to 11E3, but 10E3 is recommended for best results.
Example :CAL:PROT:DC:STEP7 10E3 Program 10kΩ step.
:STEP8 (:CALibration:PROTected:DC:STEP8)
Purpose To program the 100kΩ 4-wire comprehensive calibration step.
Format :cal:prot:dc:step8 <Cal_resistance>
Parameter <Cal_resistance> = 90E3 to 110E3 [Ω]
Description :STEP8 programs the 100kΩ 4-wire resistance comprehensive calibration
step. The allowable range of the calibration resistance parameter is from
90E3 to 110E3, but 100E3 is recommended for best results.
Example :CAL:PROT:DC:STEP8 100E3 Program 100kΩ step.
:STEP9 (CALibration:PROTected:DC:STEP9)
Purpose To program the 1MΩ comprehensive calibration step.
Format :cal:prot:dc:step9 <Cal_resistance>
Parameter <Cal_resistance> = 900E3 to 1.1E6 [Ω]
Description :STEP9 programs the 1MΩ comprehensive calibration step. The allowable
range of the calibration resistance parameter is from 900E3 to 1.1E6. Use the
1E6 value whenever possible, or the closest possible value.
Example :CAL:PROT:DC:STEP9 1E6 Program 1MΩ calibration step.
